Abstract: A display apparatus is provided. The display apparatus may include a plurality of Light Emitting Diode (LED) modules and a controller configured to obtain a plurality of image signals corresponding to the plurality of LED modules based on an input signal and control each of the plurality of LED modules based on the obtained plurality of image signals. The controller may be configured to delay a phase of the plurality of image signals to control the plurality of image signals to be output to the plurality of LED modules at different timings.

Abstract: A display device includes a plurality of light emitting diodes and a plurality of pixel driver circuits for driving the plurality of light emitting diodes; a panel driver including a plurality of driver integrated circuits (ICs) and a first switching element; a timing controller including a second switching element; and a signal transmission line connecting the first switching element and the second switching element. The timing controller is configured to control the first switching element and the second switching element to transmit an image data signal from the timing controller to the panel driver through the signal transmission line during a first time period, and control the first switching element and the second switching element to receive a state data signal of the display panel from the panel driver through the signal transmission line during a second time period different from the first time period.

Abstract: A power supply and a plasma display device having the power supply is disclosed. The power supply reduces power used in a power factor correction unit and a DC converter by distributing the total power of the power supply between the power factor correction unit and the DC converter.
